Considering aryl azides as electrophilic partners for the TosMIC mediated Van Leusen reaction, a novel multicomponent synthesis of 4-tosyl-1-arylimidazoles is reported. In this transformation, two molecules of TosMIC participate in the reaction mechanism in two different ways, with the second molecule undergoing a novel type of fragmentation resulting in the incorporation of a C-H into the final product
考虑到芳基叠氮化物是TosMIC介导的Van Leusen反应的亲电分子,据报道,有一种新颖的多组分合成4-tosyl-1-arylimidazoles的方法。在此转化中,两个TosMIC分子以两种不同的方式参与反应机理,第二个分子经历了新型的断裂,导致CH结合到最终产物中。
